20399432 divided by 398 
We want to divide 20399432 by 398.

Let's proceed to step 1:
2 divided by 398 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 398

Advancing to step 2:
The number 398 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 398

Let's proceed to step 3:
398 goes into 203 0 times with a remainder of 203.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 203, we end up with 203.
Grab the next digit (9) from the dividend, add it to 203, then carry on: 2039 / 398

On to step 4:
When dividing 2039 by 398, we get 5 with a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 1990 from 2039 and we're left with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 398

On to step 5:
398 goes into 499 1 times with a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtract 398 from 499 to get 101.
Grab the next digit (4) from the dividend, add it to 101, then carry on: 1014 / 398

On to step 6:
398 goes into 1014 2 times with a remainder of 218.
Put 2 as the next digit of the answer. 
Result so far: 512.0
If we take 796 away from 1014, we end up with 218.
Bring next digit (3) of the dividend behind the 218 and repeat the process: 2183 / 398

Let's proceed to step 7:
When dividing 2183 by 398, we get 5 with a remainder of 193.
Put 5 as the next digit of the answer. 
Result so far: 5125.0
If we subtract 1990 from 2183, we get 193.
Fetch the next digit (2) from the dividend, attach it to 193 and continue: 1932 / 398

On to step 8:
The number 398 fits into 1932 4 times, leaving a remainder of 340.
Put 4 as the next digit of the answer. 
Result so far: 51254.0
If we subtract 1592 from 1932, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 9:
The number 398 fits into 3400 8 times, leaving a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 51254.8
If we subtract 3184 from 3400, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 10:
If we divide 2160 by 398, we get 5 and a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 51254.85
Deduct 1990 from 2160 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
398 can be fit into 1700 4 times, resulting in a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 51254.854
Deduct 1592 from 1700 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 12:
1080 divided by 398 is 2 with a remainder of 284.
The next digit of our result is 2. 
Result so far: 51254.8542
Subtract 796 from 1080 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 13:
398 goes into 2840 7 times with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 51254.85427
Subtract 2786 from 2840 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
When dividing 540 by 398, we get 1 with a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 51254.854271
Subtract 398 from 540 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 15:
When dividing 1420 by 398, we get 3 with a remainder of 226.
Record the quotient 3 as the next digit in the result. 
Result so far: 51254.8542713
Subtracting 1194 from 1420 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 16:
If we divide 2260 by 398, we get 5 and a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 51254.85427135
Subtracting 1990 from 2260 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The quotient of the division is 51254.85427135, and the remainder is 2.7e-07.
